How are Persian empire and Greek empire different

The Persian Empire was an absolute monarchy which was divided intoprovinces called satrapies. Each satrapy was allowed to maintain acertain degree of ethnic and religious autonomy, provided that theyrespected the authority of the sovereign. Each of the satrapiesalso had to contribute to the massive Persian armies which wereused to bring all non-Persians under Persian rule.

There was no Greek empire. The independent Greek city-states werequite varied in political temperament. There were cities likeCorinth which were ruled by several wealthy families as anoligopoly. The overwhelming majority of the population in Spartawere non-Spartans called helots who were serfs and servants of thedominant Spartan population. Athens was a direct democracy,convening meetings of all the citizens to decide laws. Any Athenianwould have the right to speak and debate. There were other states,like Argos, that were ruled as hereditary monarchies. WhenAlexander the Great rose in the Greek region of Macedonia, he wasable to create a Hellenistic Greek empire that on his death splitup between his dictator-generals and ruled as regional kingdomswith a strong emphasis on spreading Hellenic Culture.
